Retrieving a web page via shell.explorer

[Antonio Linares]

Davide,

Some of the properties I sent you this morning allows even to be changed directly inside the ActiveX control. This way you could even change the appearance of your page locally, allowing you to use your web server as a "template" for your local application (now it's time to be really excited ).

Thats exactly how I browse the images in my demo

I modify the InnerHTML on the fly

Very useful documentation links, thanks to Davide:

"Shell.Explorer" document object:
http://msdn.microsoft.com/en-us/library/ms531073(VS.85).aspx

Navigate2 method:
http://msdn.microsoft.com/en-us/library/aa752094(VS.85).aspx

Navigate2 method:
http://msdn.microsoft.com/en-us/library/aa752094(VS.85).aspx

Main problem here is how to translate a string like "user=username&password=mypwd" into a ByteArray (please see sub PackBytes() at http://support.microsoft.com/kb/167658) in order to do:

oActiveX:Do( "Navigate2", cURL, , , vPostData, "Content-Type: application/x-www-form-urlencoded"+CRLF)

Once this is solved we can post data to a script on a server (any script on the internet) and retrieve the dynamically generated page directly in the oActiveX object.

Now we are talking!

Davide,

Here you have it. Lets try it

I am calling CreateObject() so the OLE engine is properly initialized. Not needed once we use the ActiveX. Here it seems to work fine, at least there are no GPFs and it is returning a string.

test.prg

Code: Select all  Expand view

#include "FiveWin.ch"

function Main()

   local oExplorer := CreateObject( "shell.explorer" )

   MsgInfo( GetPostData( "user=username&password=mypwd" ) )
   
return nil   

#pragma BEGINDUMP

#include <hbapi.h>
#include <windows.h>

HRESULT hb_oleVariantToItem( PHB_ITEM pItem, VARIANT * pVariant );

HB_FUNC( GETPOSTDATA )
{
   VARIANT vPostData = {0};
   LPSAFEARRAY psa;
   LPCTSTR cszPostData = hb_parc( 1 );
   UINT cElems = lstrlen( cszPostData );
   LPSTR pPostData;

   VariantInit( &vPostData );

   psa = SafeArrayCreateVector( VT_UI1, 0, cElems );
   if( ! psa )
   {
      hb_retnl( E_OUTOFMEMORY );
      return;
   }

   SafeArrayAccessData( psa, ( LPVOID * ) &pPostData );
   memcpy( pPostData, cszPostData, cElems );
   SafeArrayUnaccessData( psa );

   V_VT( &vPostData ) = VT_ARRAY | VT_UI1;
   V_ARRAY( &vPostData ) = psa;

   hb_oleVariantToItem( hb_param( -1, HB_IT_ANY ), &vPostData );
}

#pragma ENDDUMP

Davide, Patrick,

Got it working!

This is FUN isn't it??
Show us!

Patrick,

Please provide me a php from a https site, like this:

https://www.test.com/test.php // or from a subdomain, doesn't matter

and tell me what values to post, and display them from your php, and I will build the test in a moment

[Antonio Linares]

In example:

test.php

Code: Select all  Expand view

<? echo "This is a test\n"; ?>
<? echo $HTTP_POST_VARS['first']; ?>
<? echo $HTTP_POST_VARS['last']; ?>


[Antonio Linares]

Patrick,

Never mind, it is not needed. I am building the test on our secure server

Just a moment...

Ok!

This is the code:

test.prg

Code: Select all  Expand view

#include "FiveWin.ch"

function Main()

   local oWnd, oActiveX
   
   DEFINE WINDOW oWnd
   
   @ 0, 0 ACTIVEX oActiveX PROGID "Shell.Explorer" OF oWnd
   
   oWnd:oClient = oActiveX
   
   ACTIVATE WINDOW oWnd ;
      ON INIT oActiveX:Do( "Navigate2",;
                           "https://www.fivetechsoft.com/secure/english/test.php",,,;
                           GetPostData( "first=fivewin&last=FiveTech Software" ),;
                           "Content-Type: application/x-www-form-urlencoded" + CRLF )
   
return nil


Here you can download the EXE:

Besides the published GetPostData() source code, a modified Class TActiveX is required that will be included in next FWH build.

[Patrick Mast]

Antonio,

Works just fine here! Congrats!
This opens so many posibilities!

Patrick

[Davide]

Antonio,
great! now we can really communicate with the world.
I'm looking forward for the next FWH build.
Hi

Antonio,

I just want to post some data to my web page, but i don't want to see any explorer screen. Can I do it your last example?

Thanks,
